>I find myself with time on my hands today (unexpected client issue) so can try the whole thing again and get back to you with what happened. Where can I download the trial version?

It is on UT in the download section (see ID #30448) -- it is not a trial version; fully working. I just have not generally released the source at this point. I may release the source via VFPx as a community project, but have to first check on the issue of the main editor as it is licensed to me (I bought a developer license). I believe the VFP classes do not support the developer license of active x (bypasses the checks) controls. What is distributed is a run-time version of the control and not a developer version of the control.
